Low-bed semi-trailers are usually used to transport heavy-duty trucks (such as tractors, buses, special vehicles, etc.), rail vehicles, mining machinery, forestry machinery, agricultural machinery (such as excavators, bulldozers, loaders, paving machines, etc.) For cranes, etc.) and other heavy-loaded goods, the lower the center of gravity, the better the stability and safety, and the stronger the ability to transport ultra-high goods and pass overhead obstacles.
Low-flat semi-trailer trucks are also very extensive, suitable for the transportation of a variety of machinery and equipment, large objects, road construction equipment, large tanks, power station equipment, and various steel materials.
Low-bed semi-trailer structure and loading
Low flatbed semi-trailers usually use concave beam (or well-shaped) frame, that is, the front part of the frame is a gooseneck (the traction pin of the front part of the gooseneck is connected with the traction saddle on the tractor, and the back end of the gooseneck is connected with the semi-trailer frame Connected), the middle section is the cargo platform (the lowest part of the frame), and the rear end is the wheel frame (including wheels).
When loading mechanical equipment on a low-flat semi-trailer, the mechanical equipment is usually loaded from the rear of the semi-trailer, that is, the mechanical equipment is moved from the rear wheel frame or the wheels are removed, and then the mechanical equipment is fixed on the semi-trailer superior.
1. The low-flat semi-trailer series have flat, concave beam and tire exposed structures, and the longitudinal beams are straight or gooseneck. The frame is stepped, and the cross section of the longitudinal beam is I-shaped, which has the characteristics of high rigidity and high strength.
2. The main plane of the frame and cargo platform is low, which ensures the stability of transportation and is suitable for carrying all kinds of construction machinery, large equipment and steel.
3. It adopts three-axis balanced, two-axis balanced or rigid suspension, with mass balance blocks installed between the front and rear leaf springs, which can make the deflection of the front and rear leaf springs be changed by the same amount, and balance the forces on the front and rear axles.
4. The low-flat semi-trailer series products are suitable for the transportation of a variety of mechanical equipment, large objects, road construction equipment, large tanks, power station equipment, and various steel materials. It has a wide range of uses and is efficient and fast. The whole vehicle adopts advanced computer-aided design software, which is optimized for flexible and diverse design. The load-bearing surface of the frame is designed according to user requirements to meet the transportation of various special goods.
